fbs (fman build system) is a Python-based build system for creating and packaging cross-platform desktop GUI applications built with Qt (PyQt5/6 or PySide2/6). It wraps PyInstaller and NSIS to handle packaging, installers, code signing, and automatic updates on Windows, Mac, and Linux.

Use cases

package a PyQt app into an installer
create a desktop app with Python and Qt
alternative to Electron for lightweight desktop apps
distribute a Python GUI app on Windows, Mac and Linux
add automatic updates to a PyQt application
code sign a Python desktop application

When to choose

you are building a Python + Qt desktop app and need easy packaging and installers
you want a lightweight Electron alternative
you need cross-platform distribution with auto-updates out of the box

When to avoid

your app is not a GUI desktop application
you need a permissive license for closed-source use without buying fbs Pro
you prefer configuring PyInstaller and platform installers yourself
